S16 mounting suggestions

Hello. Anyone have any suggestions for mounting the S16 base unit for a residential entrance (door station) application? We are planning on installing the dual camera mount at the top door frame, but struggling to find a location for the S16 base unit. Installing the unit on/within the inside entrance wall is not really an option. Any suggestions on outside mounting as the unit is weather-proof as I understand, maybe some type of enclosure that can mounted to the vinyl siding out of reach?

Thank you in advance.
